Abstract
In recent decades, hydrogen peroxide (H
2 O 2 ) has attracted considerable attention as a n
omnipresent analyte, finding applications in clinical studies/diagnos is , biology,
environmental protection, atmospheric studies, homeland security, and various analytical
methodologies . This dissertation provides valuable insights into three different types of
electrochemical sensors specifically designed for the detection of low concentration levels
of gaseous H 2 O 2 . T heir stability, detection limits, sensitivity, repeatability, ability to
analyze real sample s , and challenges encountered in their practical application are
examined
In
addition , the dissertation delves into a discussion of the advantages and
disadvantages associated with the implementation of different
sensing/modification /functional materials in the design of H 2 O 2 sensors. These materials
encompass a range of options s uch as 2D materials (MXenes), polymeric substrates,
metal oxides, and redox active compounds such as ferrocyanide, all aiming to enhance
electrochemical sensor performance.
Furthermore,
considering their inherent advantages and limitations, the future
pros pects of these sensors are examined alongside potential scenarios for their application
in indoor/outdoor H 2 O 2 monitoring.
Doctoral
dissertation provides comprehensive insights into the development and
evaluation of sensitive electrochemical sensors for gaseous H 2 O 2 detection, highlighting
material selection , performance improvements, and future opportunities for their
application in monitoring H 2 O 2 in various environments.
